Application filed January 4. 1912. Serial No. 669,372.

To all whom itmag concern: a

Be it known that we, \VILLIAM O. ASH- LOCK and HENRY H. AsHLooK, citizens of the United States, residing at San Diego, in the county of San Diego, State of California, have invented a new and useful Heater for Automobiles, of which the. following is a specification. I

This invention relate to heaters for, automobiles, its principal object being to utilize the waste heat radiating from the exhaust pipes of the motor, for the purpose of heating the interior of the tonneau.

A further object is to provide means whereby the flow of the heating medium into the tonneau may be controlled.

A further objectis to mount the heater. .detachablyso that the same can be applied to or removed from the exhaustpipes easily of motor vehicles already in use.

VVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in-the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, Without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown:

In said drawings :Figure 1 is a side elevation of the attachment in position, the heat conducting pipes being shown in section. F ig. 2 is an-end elevation of the attachment. Fig. Fig. l. s

Referring to the figures by characters of reference C designates a motor of the ordinary type and fromwhich extend exhaust pipes D opening into a manifold'E to which the m'ufiier F is connected. I

The tonneau of the car isadapted to 'be provided, at suitable points,-with regopen and has a valved whereby. said end .is open the heated air can be closed or opened as desired for the purpose of controlling the pamage of? the heating medium through the pipes. A flange 5 is formed on the other end portion of the main pipe 2 and is adapted to be coupled, detachably, to the heatingattachment constituting themain portion of the present invention. This heater consists pcsitely disposed hingedly connected casing sections 6 adapted to fit snugly around the exhaust pipes D close to the motor C and also to fit snuglyaround the projecting end portion of the manifold E so as to thus form an air space around the manifold and the exhaust pipes. An inlet opening 7 is formed at the front has a funnel-like wall 8 for directing air into the opening 7. tends from the back, end of the casing and is adapted to be coupled to the flange5.

of two opend of the casing and An outlet pipe 9 ex- The inlet 7 is-arranged backof and close 7 to the edge of cooling fan G and the circulation of air set up by this fan and also caused by the forward movement of the car will cause air to enter the opening 7 and flow around the manifold E and theexhaust pipes D. The air will thus'be thoroughly.

heated and will pass outwardly through pipe 9 into the main pipe 2. If the valve 4 will pass out the rear end of the pipe. If, however, the valve 4 is closed, the heated air will flow outwardly, through the pipes' 1 and into the registers or radiators, not shown, the flow of the heating medium through the pipes 1 being controlled bythe pipes or dampers 3. 3 is a section on line AB Importance is attached to the fact that the heater constituting the present invention can be quickly applied to ordinary motors simply by swinging apart the casing sec-' tions and positioning them at opposite sides of the manifold and exhaust pipes after which the sections can be moved toward each other and secured by means of bolts 10 extending throughears 11 or the like projecting from the upper or free edges of the casing sections 6. ,The pipe 9 is preferably formed in two pieces hingedly connected, one section of the pipe being movable with each section of the casing 6. It is to be understood, however, that if preferred the pipe 9 can be extended from only one of the sections of the casing 6, in which case it will not be necessary to form the pi e in two pieces. The funnel-like wall 8 of toe inlet opening 7 'isalso preferably formed of sections but it is of the device much as said devlce can hot weather.

already in use, it is to be understood, that if desired, the device can be formed upon the motor at the factory, in which event, the attachment need not be detachable although itis to be understood that the detachability is an important feature inasbe removed during It is to be understood that the attachment constituting the present invention is preferabley to be covered with asbestos or other heat non-conducting material such as shown at 12 in Fig. 8.

hat is claimed is The combination with a motor having a manifold, of a casing made up of opposed l connected sections, one of said sections be- 1 ing' insertible between the manifold and the l cylinders of the motor and the other section being movable against the manifold and between the tubes thereof, thereby to house the manifold-between the sections, means for detachably securing the manifold and sections together, said sections cooperating to form an air inlet at their front ends, an air distributing; pipe for directing air into the body of an autmnobile from the rear end of the casing, said casing being reduced toward the pipe, said casing being adapted to be bodily released and"l owered from the main fold in Warm weather.

In testimony that We claim the foregoing as our own, we have hereto ailixed our signatures in the presence of witnesses.
